Shape Memory Metal

The goal of the experiment was to heat the shape memory alloy to see if the metal will revert back to its original shape. In order to do so I needed a hair dryer with a low and high setting, and a shape memory paperclip. How I went to test this was I took the paper clip, straightened it out, and then heated the paper clip with the blow dryer. In order to obtain accurate results, I needed to do four trials with the blow dryer on the high setting, and one trial with the blow dryer on a low setting. To begin the experiment I first took the shape memory paper clip and I straightened it out. Next I took the blow dryer and put it on high. After that I took the blow dryer and heated the shape memory paper clip. Last I took down observations of what I noted. What I took notice too was the paper clip reverted to its original paper clip shape within seconds of being heated. I repeated this process a second time and noticed that it did the exact same as the first trial with no signs of deformation from straightening the paper clip. Once again I repeated the process for a third trial. This trial proved to be the same as the first two, with reverting to its original shape within seconds. On the fourth, and last, trial the results were no different the previous three trials. The paper clip showed no signs of deformation from any of the four trials and the paper clip reacted the same to the heat all four times as well. For my fifth trial I was instructed to heat the paper clip at a low setting. With the blow dryer on a different setting this created different results. After straightening out the paper clip I heated it with a low setting. The observations I made were the paper clip took a longer time to revert to its original shape. I also took note that the paper clip did not quite make it back to its original shape. The results taught me how the shape memory alloy reacts to different temperatures.

    An alloy is a solid solution or homogeneous mixture of two or more elements where a material with better or different properties is produced. The range of alloys produced depends on the solubility of the constituents and the proportion of them. The number of possible alloy combinations is almost endless since any metal can be alloyed in pairs or in multiples. Alloys can be classified into two main categories:Interstitial alloy. It is when smaller elements, such as boron, carbon, nitrogen, or silicon…

     Introduction Brasses are copper zinc alloys. It is a substitutional alloy. Brass has higher malleability than copper or zinc. In general, they have good strength and corrosion resistance, although their structure and properties are a function of zinc content. The relatively low melting point of brass (900 to 940°C, depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can…

    1. In general, why have many different alloys been developed and used? Many different alloys have been developed and used due to the various properties they have when alloyed which increase their amount of uses. Properties such as increased tensile strength, the variation in melting point, malleability and luster are all properties that come as a result from alloyed metals. For example, carbon and manganese form an alloy called carbon steel, which is very hard and can therefore be used to make things…
